grml2hd: use UUID for root-device (issue93), provide dialog for dis-/enabling services (issue89), support for grub within grml2hd itself (issue81)

Of course resolving the other issues on grml's BTS is on the todo list as well. Features like unionfs-overlays and additional squashfs-files are on the wishlist too of course. My plan is to release grml 1.0 in march 2007. Needs a lot of work of course...
